"Is possessing the material different?"

I mean...yes? of course it is?

It's like pretending to watch a football match on tv to be materially the same as being in the field.

There is of course the question of whether he shared it or not, or if it was just for personal use, but still, as horrible that subject might be, I'm more than a bit mystified at the idea of the act vs. watching the video of the act considered as being even remotely in the same ballpark.
